The honest details.
Where do the prices come from?
We read prices directly from UK shop product pages and refresh them regularly. Each price shows when it was last checked, so you know how current it is.
How often are prices updated?
Automatically every day. Each filament shows a "checked X hours ago" note so you can judge freshness yourself.
Are you affiliated with these shops?
No — LayerNomics is independent. We are not paid by any retailer and the cheapest-first ranking is never influenced by commercial relationships.
Why is a price different when I click through?
Shops change prices and we refresh on a schedule, so always confirm the final price on the shop's own page before buying.
Can I add a price or shop?
Yes — community price submissions help keep coverage broad. Use "Submit a price" in the menu.
